Genus Argynnis 



yellow at the apex of the primaries contrasts much more strongly. 

 The spots on the under side in the female sex are frequently well 

 silvered, though in many specimens they are colored exactly as 

 in the male sex. Expanse of wing, $, 2.17 inches; ?, 2.50 

 inches. 



Early Stages. — The early stages of this species have not as 

 yet been ascertained. 



This beautiful butterfly, which is somewhat inclined to varia- 

 tion, is found in northern California, being quite common about 

 Mount Shasta. It is also found in Oregon and Nevada. One 

 of the varietal forms was named Argynnis pnrpurescens by the 

 late Henry Edwards, because of the decided purplish tint which 

 prevails on the under side of the secondaries, extending over the 

 entire surface of the hind wings and covering likewise the apex 

 of the fore wings. This purplish-brown is very marked in speci- 

 mens collected about the town of Soda Springs, in northern 

 California.

Butterfly. — This species is very closely allied to the preced- 

 ing in some respects; the upper surface, however, of the wings 

 in both sexes is brighter than in :{erene, and the dark markings 

 stand forth more clearly upon the lighter ground-color. The 

 wings are not shaded with fuscous toward the base as much as 

 in A. ^erene. While the markings on the upper side are almost 

 identical with those of Dr. Boisduval's species, they are much 

 brighter and clearer, giving the insects quite a different aspect. 

 On the under side the wings are colored as in ^ereiie, the prima- 

 ries in the male being ferruginous, laved with a little red toward 

 the base, marked with purplish-gray toward the apex, the light 

 spots near the end of the cell on this wing being pale buff. The 

 hind wings are very uniformly purplish-gray, mottled with dark 

 brown, the spots very little, if at all, silvered in the male. In the 

 female the fore wings are bright red at the base, and the hind 

 wings are colored as in the male; but all the spots in both the 

 fore wings and hind wings are broadly and brightly silvered. 



Early Stages. — The early stages have not been ascertained, 

 and there remains something here for young entomologists to 

 accomplish. 



This species is quite common in the same localities as the last,
